A pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE) is provided. The device of a radio unit (RU) of a base station in a wireless communication system includes at least one transceiver and at least one processor coupled to the at least one transceiver, wherein the at least one processor is configured to receive a first control message including a section extension field from a digital unit (DU) via a fronthaul interface, identify additional information based on the section extension field, and acquire a beamforming weight based on the additional information, wherein the first control message is configured to schedule a terminal in a control plane.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the section type 5 is defined in an open-radio access network (O-RAN).
4. The method of claim 1, wherein the regularization factor is associated with a noise variance used for the MMSE calculation.
5. The method of claim 1, wherein the regularization factor is transmitted to the RU from the DU instead of a section type 6 for channel information.
7. The method of claim 1, wherein a value of the management plane message indicates that the regularization factor is transmitted in section extension information of the section type 5 or the regularization factor is transmitted in another section type.
9. The method of claim 8, wherein the section type 5 is defined in an open-radio access network (O-RAN).
11. The method of claim 8, wherein the regularization factor is associated with a noise variance used for the MMSE calculation.
12. The method of claim 8, wherein the regularization factor is received from the DU instead of a section type 6 for channel information.
14. The method of claim 8, wherein a value of the management plane message indicates that the regularization factor is included in section extension information of the section type 5 or the regularization factor is included in another section type.
16. The device of claim 15, wherein the section type 5 is defined in an open-radio access network (O-RAN).
18. The device of claim 15, wherein the regularization factor is associated with a noise variance used for the MMSE calculation.
19. The device of claim 15, wherein the regularization factor is transmitted to the RU from the DU instead of a section type 6 for channel information.
21. The device of claim 15, wherein a value of the management plane message indicates that the regularization factor is transmitted in section extension information of the section type 5 or the regularization factor is transmitted in another section type.
23. The device of claim 22, wherein the section type 5 is defined in an open-radio access network (O-RAN).
25. The device of claim 22, wherein the regularization factor is associated with a noise variance used for the MMSE calculation.
26. The device of claim 22, wherein the regularization factor is received from the DU instead of a section type 6 for channel information.
28. The device of claim 22, wherein a value of the management plane message indicates that the regularization factor is included in section extension information of the section type 5 or the regularization factor is included in another section type.
